LM-LP-1002L

Overview

The LM-LP-1002L is a line matching transformer from the Bourns LM-NP/-LP 1000 Series, designed for audio signal applications. It features a 1:1 turns ratio and provides an isolation voltage of 6500VDC. The primary winding has a DC resistance (DCR) of 90 Ohms, while the secondary winding DCR is also 90 Ohms. The unit utilizes a five-terminal configuration with PC pin through-hole mounting. Key electrical specifications include an inductance of 2.8H and a primary impedance of 90 Ohms.

Feature Summary

• Provides galvanic isolation between audio circuits with high dielectric strength
• Maintains signal integrity through precise 1:1 line matching characteristics
• Supports robust mechanical installation via five-terminal through-hole PC pin design

Applications

• Audio line matching in professional sound systems
• Signal isolation in broadcast equipment
• Interfacing between audio stages requiring balanced transmission

Procurement Notes

Verify the specific part number suffix against official Bourns documentation to confirm exact electrical tolerances and physical dimensions. Ensure that the procurement request aligns with the manufacturer's standard lead times and ordering guidelines. Cross-reference the component details with the latest datasheet to confirm compatibility with the intended circuit requirements before finalizing orders.

Selection Notes

Select this component when a 1:1 transformation ratio and 90 Ohm impedance are required for audio line matching. Consider the 2.8H inductance value for low-frequency response needs. Evaluate the through-hole package constraints and five-terminal layout against the printed circuit board design. Confirm that the 6500VDC isolation rating meets the safety requirements of the application environment.
